Product overview
Western Digital lists WD1003FBYX-18Y7B0 as a RE4 1TB 7200RPM SATA 64MB 3.5-Inch Enterprise hard Drive. Vendor-keyed firmware is the usual reason a mechanically identical drive is rejected by the controller, and a 1TB spare is not worth discovering that on. We check the firmware family against your controller before the drive ships.
Quote requests are answered within 48 business hours, with availability confirmed before you raise a purchase order rather than after.

A quote comes back with the reasoning attached, including the cases where we think you should buy something else.
Compatibility checked
We confirm the part is supported on your platform before it ships, rather than leaving the check to you.
Questions buyers ask about this part
- Is WD1003FBYX-18Y7B0 genuine and is the warranty intact?
- Yes. Supplied new and unopened, so the manufacturer warranty and firmware update path stay supported. No grey-market stock and no refurbished units sold as new.
- Will WD1003FBYX-18Y7B0 work in my server?
- Send the server model or the shelf it is going into. Vendor-keyed firmware is the usual reason an identical-looking drive is rejected, so we check that alongside interface and form factor.
- Do you accept purchase orders and quote at volume?
- Yes. Purchase orders are accepted from qualified organisations, net terms are available on approval, and tiered pricing applies at quantity. Tell us how many you need.

Specifying a system, not just the part?
Bulk capacity usually sits behind the flash tier that feeds a training cluster rather than under it.
